Frostburn and Blistering Scorn for mass removal.
Artifacts go well with Concealing Shroud. Try Snowpiler or White Asp. White Asp and Winterblade may be helpful if comboed with Coldbiter.
Bring in some “standard” minions for Faie also. Stuff like Crystal Cloaker and Snowchaser are must-include in most Vanar decks.
You may want more removal options. Aspect of the Wolf is a versatile one: you can use it both offensively (transforming a Gravity Well of yours into a wolf) or defensively (turning smth like Aymara or Noah-Rak into a relatively harmless wolf). Repulsor Beast is a nice option also.
Since you’re including quite an amount of walls in your deck, you may as well add in more wall synergy, like Winter’s Wake and Blazing Spines.
Lastly, you need some card draws. I like L’Kian and Crygenesis. Some others prefer Spellbender or Sonourner instead of L’Kian because of the consistency (Cards L’Kian pull may not be too helpful)
